Leaf curling, but stretching aswell.

Hey,

I've got 4 plants and I'm running 2 x 600w HPS
Plants are in autopots, I'm on week 6 of flowering but they seem to be behind because I chopped off a lot of branches at the start of flowering.
If it was just the curling then I wouldn't bother posting but, the top branches seem to be stretching and not growing as well as the lower ones and I'm not sure where to start on trying to fix it.

A bit overfertilized. No big deal just give straight water a couple times.

Classic signs of N toxicity. Dark green leafs and they curl downwards. Leaf's curling upwards means too much heat. Go easy on the nitrogen!

Also, what is your lighting schedule? they seem to be a bit foxtaily?

Oh and, since you are at 6 weeks flowing, if they are mainly indica dominant you should be reducing your ferts and start flushing week 7-8 of flowering.

Thanks for he replies, I suspected the nitrogen. I already started reducing my nutes but I'll just give them water for a bit. I'm in week 6 but I reckon they won't be ready for another 3-4 weeks.
